I can sympathize because we usually get 200-300 kids. However, a few big bags of smarties or dum dum pops aren't that much. If need be, you can turn off the lights when you run out.
As kids we hated getting those. We wanted and thankfully got the good chocolate. We give out the good chocolate. The kids get 5-6 different kinds in the bags. It is really not that expensive. We get 100 kids. I wish we got more. I love Halloween
OP ditch the idea and just turn off the lights.
(I think that will be heavy for the kids to carry around and what if they drop their bag oh no now I am really worried about this. LOL) and a few bags of candy bars and I know she didn't spend more than $50 and she will just turn out her lights if she gets more kids than that.
. The can of soda came from a guy who lived alone in his house and I think was just finding random stuff in his house to give to kids. I loved it!
